Results

The comparatively less sensitive Farnsworth panel D-15 test failed to show any difference between the groups, but the Lanthony panel D-15 desaturated test as well as the SPP2 test showed a significant impairment in the exposed group.

Errors were of the blue-yellow type.

Conclusion

This study gives further evidence that even mixtures of organic solvents at concentrations below the threshold-limit values may impair color vision.
